Definition

 virtual void OnMouseWheel(System::Windows::Forms::MouseEventArgs ^ e);
protected virtual void OnMouseWheel (System.Windows.Forms.MouseEventArgs e);
abstract member OnMouseWheel : System.Windows.Forms.MouseEventArgs -> unit
override this.OnMouseWheel : System.Windows.Forms.MouseEventArgs -> unit
Protected Overridable Sub OnMouseWheel (e As MouseEventArgs)

Parameters

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnMouseWheel method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors

When overriding OnMouseWheel(MouseEventArgs) in a derived class, be sure to call the base class's OnMouseWheel(MouseEventArgs) method so that registered delegates receive the event.
